By has Azftorney Patented Nov. 11, 1952 PAD BOX Charles G. Melanson, Lynn, Mass., assignorto United Shoe Machinery Corporation, Flemington, N. J., a corporation of New Jersey Application March 29, 1951 Serial No. 218,176 12 claims. (Cl. izss) This invention relates to pads and pad boxes for use in machines for applying-pressure to shoe bottoms.

Objects or" the invention are to provide a pad support which is readily adjustable to the longitudinal contours of shoe bottoms irrespective of the height of the heels thev shoes are tohave and which is transversely curved to correspond to the transverse curvature of the shank-andheel portions of shoe bottoms.

To this end the pad support is made in two parts, i. e., a support for the forepart of the pad movable about an axis located substantially in the surface of the pad at the ball line of the shoe and a support forv the shank-and-heel portions thereof, said support having a horizontal surface to engage the heel portion and an inclined surface to engage the shank, the support being movable in a direction parallel rto-the inclined surface to permit adjustment thereof to accommodate shoes that are to have heels of various heights.

As illustrated, the shank-and-heel support comprises a block having a horizontal surface to engage the heel portion of the shoe and an en d face inclined at about 45 tothe horizontal to engage the shank portion of the shoe, the block being mounted for adjustment ina directionparallel to said end face. `Downward adjustment of the block adapts it to accommodateshoesthat are to have heels of lesser heights'.v n

Beneath the ball portion of the padis axed supportcomp-rising a rod extendingA transversely of the pad and supported in the walls or an outer box, said rod being` linked atA its ends to a series oi` closely adjacent rolls parallel to the rod-and forming a roller blanket to lie-between the pad and the shank-and-heel portion supporting surfaces of the block. As'illustrated, the rolls may be small in the middle Vand gradually increase in size toward the ends, thus providing apad-supporting surfacewhich is transverselyy concave to accommodate the transverse convexity of the shank portion of the shoe bottom. To support the rolls, the surfaces of the block underlying them may be made convex to an extent corresponding to. theconcavity of the rolls. Thus, the

support for the shankand heel portion allows theY pad to conform closelyjto the` transverse curvature of the shank-and-heel portionof a shoe bottom. Each roll is a-solid generated by the revolution of a conicabout an aXisin its planeandfis therefore va tore. Each rollis mounted for rotation on its longitudinal a-x-is Ona rodre'aoh. end; of which is connected to a; chain.

The support for the forepart of the p ad is cali; ried by an inner box and,.since adjustment of the forepart support about an axis in the surface of the pad to. increase its inclination moves the end of the support adjacent to the fixed rod away from the rod, means iS. plovidedfor adjusting the inner box longitudinally otthe pad relatively tothe. outer boX. thus `enabling the inner end of the iorepart` support to be maintained under the ball line and4 adjacent to the rod irrespective of the amount the forepart support is tipped upwardly about its axis.

The illustrated pad` support cornwprisesan4 outer box having a bottom 20, side walls 22, 23 and a partial end Wall 24` at its-heelend. Within the box beneath the forepart oi a pad 2B of rubber or the like is an Iinner box having a bottom 2s, sideA walls` 3l),v 3.! and @partial end Wall` 32,' at

its toeward end. Thev outerI boxhas adjacent to.

its corners finished surfaces 33 (Fig. 4) engaging similar surfaces on the inner box to facilitate` sliding of the innerV box relatively to the outer. The partial endw'all. 3'2 of the inner boxl (Eig. 3.) is connected to. anear`34j on the bottom 20 of the outer vbox by a screw 36 rotatably mounted in the ear 3.2i and threaded through .the'vall 32. On the screw/,'36 is` a knobf38 by` which it may be turned to. adjust the inner boxlongitudinallyoi' the outer' box. which constitutes a support forV the `f'orepart of thepad. At each side of the cover is attached by screws fiZfa segment gear' 44 which has a'circular gib it larranged to slide inacorresponding groove di. (Fig. l) in the'inne'r side of one of thewalls 3G, 3l" of the innerV box. Preferably the gear segments llsar'e integrally'connected by a web 48 and the circular gibs 46 are formed about a 4center 5,0 located substantially in the upper sur'- face. of the padwhere it will be engaged by the b all line ofthe shoe. AtI the,` centers 5t)Vv (Fig. 1,)

on eachside ofthe box there are pins threadedl onethroughv ,each .side of they boX and extending agshort; distanoeinto the nad to hold the part of The inner box has a cover 40' the pad engaged by them fixed while the front and rear portions `are adjusted vertically. Pinions 52 iixed to a shaft 54| journaled in the walls 30, 3| of the inner box mesh with the gear segments 4B. One end portion of the shaft 54 extends through a slot 56 in the side wall 22 of the outer box, the slot extending horizontally to permit adjustment of the inner box relatively to the outer.

Loosely mounted on the shaft 54 is a disk 58 having a fiat sided hub portion B (Fig. 4) tting the slot 56 so that it can move endwise of the slot but cannot turn therein. A handle 62 fixed to the shaft 54 carries a spring plunger 64 which may engage any one of a series of holes 65 near the perip-hery of the disk 58.

By pulling the spring plunger 64 out of its hole and turning the shaft 54 by its handle 62, the pinions 52 may be turned`to adjust the cover 40 about the center 50. Since upward tilting of the toeward end of the cover 40 about its center moves its lower end away from its position under the ball line, the screw 36 is provided by turning which the cover 40 and the inner box may be moved bodily toward and from the ball line as permitted by the slot 56. Beneath the shankand-heel portion oi the pad is a series of rolls T0 which may be cylindrical or may, as shown in Fig. 2, be small in the middle and gradually increase in size toward the ends, each roll being in form a tore as above explained. The end roll 'l2 under the ball of the pad is larger than the others and is supported by a rod 14 passing through the sides 22, 23 of the outer box, this rod constituting the only fixed point of the pad support. The rolls '|0, 'i2 are connected at their opposite ends by chains 1B which hold them together as a exible unit or blanket extending throughout the shank-and-heel portion of the pad.

Beneath the rolls 'I0 is a block 18 having rectangular portions '9 mounted to slide in ways 80 formed in the inner faces of the sides 22, 23 of the outer box and inclined at about 45 to the bottom 2t of the box. The end and top surfaces of the block 18 which engage the rolls 10, '|2 may be complemental to the surfaces of the rolls engaged by them, the end surface 82 being substantially parallel to the ways 80.

The block is moved along the ways 80 by -a rack 84 secured at 8B to the block 18 and engaging a pinion 88 fixed to a shaft 90 mounted to rotate in the sides 22, 23 of the outer box. An arm 92 secured to the shaft 90 is provided with a spring plunger 94 similar to the plunger 64 already described which may engage any one of a series of holes 90 formed in the side 22 of the box to hold the block 18 in adjusted position.

The shank portions of the pad 26 may be slot ted at 98 to increase the compressibility of the pad in that region.

To control the wrap of the sole at the forepart, the cover 40 has an opening therein shaped like the forepart of a shoe sole but smaller than the orepart of the average shoe, and located in the opening is a plate |00 shaped like the opening. Means for adjusting the plate |00 perpendicularly to the cover 40 is provided by a wedge |02 xed to the plate |00 and a Wedge |04 movable endwise with respect to the wedge |02 and supported by the transverse web 48 integral with the segments 44 to which the icover 40 is secured Iby the screws 42. A screw |08 rotatably mounted in a lug I l0 on the web 48 is threaded into the wedge |04. The screw has a head ||2 by which it may 4 be turned to move the Wedge |04 and hence raise or lower the plate |00 with respect to the cover 40, When the plate is ush with the cover a normal amount of wrap will be provided which may be reduced by raising the plate or increased by lowering it.
